Air filter orientation and direction?

[armored007]

So I do have the smaller filter, does it really matter if I attach it directly to the compressor? Secondly does it matter too about the direction if I switch around the QD to the other side, reason I ask is because one side has desiccant and the other half is a filter. Thanks

The filter should be in a vertical position to werq properly. Its probly best if the filter is on the bottom so it gets the air first that way you can make your desiccant last longer by changing the filter often when it gets damp. Set the old filter out and let it dry to use later.

Curious to why the filter needs to be vertical, is it because of the water build-up?

 

[biohazardman]

Yes, moisture build up will easily pass through if it is not vertical.

Thanks. Good point to keep it vertical.

Personally I believe that the filter should be horizontal and then the hose to gun should be vertical. Here is my reasoning.

1) If the filter is vertical gravity will cause the water to keep trying to get back to the compressor, the air from the compressor will keep hitting it, causing the particles to continue to break up and get smaller, possibly eventually passing thru the filter.

2) If the filter is vertical where is the water going when you shut off your compressor? Back to compressor? I rather it sit inside the filter as opposed to inside the compressor

3) Shop compressors with air tools and spray guns hooked to them all have water filters that have a reservoir where gravity is used to keep the water inside the filter. This is how I have the my primary stage of my shoebox set up. From the small 2nd stage output filter the hose goes upward and the gun or tank being filled sits on the top shelf.

Seems gravity is the logic behind keeping the filter vertical. I certainly see what you are saying and I'm absolutely not sure which is best. Keeping it vertical makes more sense to me.

If you look at the "vertical" filter in my pic (it's actually horizontal with a vertical reservoir) there is a drain to remove water. In the pic with the Tuxing filter in a vertical position, where does the water "drain"? and where does it go?

Seems to me that it goes back to the compressor, right? To sit in the compressor to be pumped up again? Why you would want to do this makes no sense to me, but to each his own I guess.

My thought is that you are removing the water when you vent. I don't see that water could "return" to the compressor since the venting is between the high pressure cylinder and the high pressure from the compressor. Less than ideal without a drain at a reservoir? Seems so. But I still see the gross moisture that builds up as mostly leaving the system at each venting. But as you note, to each his own (especially since neither of us knows FOR SURE what is happening inside the system).
